Can I convert mbr to gpt during Windows installation without data loss
What you’ll need if you are going to convert MBR to GPT during windows installation:
1. Windows installation media (USB or DVD).
2. A backup of your important data (just in case things go sideways).
Step-by-Step Guide:
1. Boot from Installation Media:
- Pop your Windows installation USB or DVD into your computer and restart it.
- Make sure to get into the BIOS/UEFI settings (usually by hitting F2, F10, DEL, or ESC right when your computer starts) and set your boot order to boot from the USB/DVD first.
2. Start the Installation: Once your computer boots up from the media, you’ll get to the Windows Setup screen.
3. Access the Command Prompt:
- When you get to the screen where it says "Install now," look for the option that says “Repair your computer.”
- Click on that, then go to “Troubleshoot,” and from there, select “Command Prompt.”
4. Open Diskpart: In the Command Prompt, type diskpart and hit Enter. This will launch the disk partition utility.
5. List Your Disks: Type list disk and press Enter. You’ll see all the disks connected to your system.
6. Select Your Disk:
- Find the disk you want to convert to GPT. It’s usually Disk 0 if it’s the primary drive, but just double-
- check. Type select disk X (replace X with the number of your disk) and hit Enter.
7. Clean the Disk:Warning: This will erase everything on the disk, so make sure you have your backup. Type clean and hit Enter. This wipes everything off that disk.
8. Convert to GPT: Now type convert MBR to GPT, just hit Enter. This will convert your clean disk to GPT.
9. Exit Diskpart: Once that's done, type exit to leave the diskpart tool.
10 Proceed with Installation: Now you can close the Command Prompt and go back to the Windows Setup. Select “Install now,” and you should be able to see your disk formatted as GPT. Just follow the prompts to install Windows.
